Abstract
The utility model discloses an intelligent thermal controller, comprising a control circuit, a digital temperature sensor, a display and a relay circuit, wherein the digital temperature sensor is connected with an input end of the circuit; the display and the relay circuit are connected with an output end of the control circuit. The digital temperature sensor is cooperated with the display to display and the temperature control precision is increased with feedback control function; simultaneously the control circuit provides automatic heating and thermal-insulation control function at the cold condition, furthermore the product performance is optimized. The intelligent thermal controller has features of good reliability and strong practicability and is suitable for the situation with heating thermal-insulation control requirement, especially suitable for situations with requirements for controlling the warming of the clothes, food and other articles, such as hospitals, kindergartens, homes for the aged and the low-temperature work.
Description
[technical field]
The utility model relates to intelligent electric controller field.
[background technology]
There is following deficiency in the electric controller that generally adopts at present:
1. do not adopt the digital temperature sensor technology, the temperature signal precision is not high.
2. do not possess feedback control function, can not realize preservation and controlling.
3. do not adopt the microcontroller technology, controller is intelligent not strong.
4. the integrated control functions that does not have timing, heat-insulating integral.
As Chinese patent 200720013024.6, though can realize regularly electric heating control, but there is not feedback control function, can't realize preservation and controlling, do not adopt microcontroller and digital temperature sensor technology control accuracy not high, intelligent not strong, and do not have the integrated control functions of timing, heat-insulating integral.Can not satisfy the application demand of multiple occasion and environment.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of intelligent electric controller, can improve control accuracy, and have feedback control function, satisfies the application demand of multiple occasion and environment.
For achieving the above object, the utility model proposes a kind of intelligent electric controller, comprise control circuit, digital temperature sensor, display and relay circuit, described digital temperature sensor is connected to the input end of control circuit, and described display and relay circuit all are connected to the output terminal of control circuit.
As preferably, described control circuit is made of microcontroller MCU or microprocessor MP.
As preferably, described microcontroller MCU is the 89C51 chip.
As preferably, described display is the LCD LCD.
As preferably, described digital temperature sensor is the DS18B20 chip.
The beneficial effects of the utility model: the utility model adopts digital temperature sensor to cooperate display to show, improved temperature control precision, and has a feedback control function, simultaneously, the control circuit that adopts can provide the function of automatic heating and preservation and controlling under cold conditions, further optimized properties of product.The utility model good reliability, practical, be applicable to the occasion of heat tracing demand for control, being particularly useful for hospital, kindergarten, the home for the aged, low temp operation etc. has the occasion of demand to controlling warm clothing, food and other article.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the theory diagram of a kind of intelligent electric controller of the utility model;
Fig. 2 is the circuit theory diagrams of a kind of intelligent electric controller of the utility model.
[embodiment]
As shown in Figure 1, the intelligence electric controller, comprise control circuit 1, digital temperature sensor 2, display 3 and relay circuit 4, described digital temperature sensor 2 is connected to the input end of control circuit 1, and described display 3 and relay circuit 4 all are connected to the output terminal of control circuit 1.
As shown in Figure 2, the microcontroller MCU of control circuit 1 adopts the 89C51 chip, is connected with relay circuit 4 by its I/O mouth, and microcontroller is controlled the start and stop of electrothermal mechanism by managing relay on-off, realizes the control to heating; Microcontroller is connected with display 3, and display 3 is LCD display, realizes information display function; Microcontroller links to each other with digital temperature sensor 2, and digital temperature sensor 2 adopts the DS18B20 chip, accepts to convert numerical information to from the temperature information that is heated object, sends microcontroller to; Microcontroller is exported corresponding video data to display unit by its display interface, and shows; When temperature is lower than setting value, microcontroller is in the automatic heat preserving state, then directly carries out heating operation; When temperature is lower than setting value, microcontroller is in regularly heated condition, then need wait for and carry out heating operation when timing condition possesses; When temperature is higher than setting value, microcontroller stops heating operation control; The switch of relay is used to control the on/off of electrothermal mechanism, realizes the work of electrical heating operation or stops; The control of microcontroller by the switching manipulation of relay circuit being finished automatically heating and being stopped to heat, thus realize heating automatically and the control function that is incubated.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
